Support » Plugin: Jetpack by » Jetpack facebook plugin broken on MacOS

  • Resolved Adrian


    I have two sites using the JetPack facebook plugin widget in a sidebar.
    The other site is

    The facebook widget has recently stopped working on Chrome, Safari and Firefox on MacOS High Sierra 10.13.5.
    It displays no output.
    The widget still works as expected on MacOS High Sierra using the Opera browser, and it’s also fine with multiple browsers on Windows 10 (Chrome, IE, Edge, Firefox) and using Safari and Chrome on IOS 11.4.

    One site is on JetPack 5.9 and the other on JetPack 6.2.1, so the problem is unlikely to have been caused by a recent change in JetPack.

    Could there have been a change to (for example) the Webkit in the MacOS 10.13.5 update which broke the plugin?

    The page I need help with: [log in to see the link]

    Hi @adriandw

    Have you already tried disabling the Facebook plugin and reinstalling it?

    Do both of your sites run the same set of plugins? Perhaps there’s an incompatibility.

    thanks for your thoughts.
    Is it possible to disable and reinstall the Jetpack facebook widget without reinstalling the whole of Jetpack?

    My two sites run different sets or plugins (some the same and some different).

    The jetpack facebook widget has stopped working on two different sites hosted on two different servers running different hosting software and different levels of php, different levels of Jetpack.
    The common factor is that the widget now fails on MacOS 10.13.5 for all tested browsers except Opera, but it works fine on other platforms (IOS, Windows 10).
    Have you tried accessing those two URLs from a MacOS High Sierra system? What happened?



    I’ve made some more tests.
    I tried disabling all plugins except Jetpack to see if there was a conflict. No difference.

    Situation is
    If I access a site running the jetpack facebook widget, the widget displays no output when I’m using MacOS High Sierra 10.13.5 and either Chrome, Safari or Firefox browser.
    It works fine with the Opera, Yandex or Chrome Canary browsers.
    It also works fine with Chrome, Safari or Firefox if I boot from a backup drive which is still on High Sierra 10.13.4

    I’ve tested multiple browsers on Windows 10 and IOS 11.4 without problems.

    Are you able to access my test site from a machine running MacOS 10.13.5 and see if the widget produces any output for you?

    I am able to see the Facebook widget with the Litter Cleanup event on June 30th via my Chrome browser on MacOS 10.13.5.



    then maybe it’s a problem with a browser extension that is affecting my instances of Chrome, Firefox and Safari on 10.13.5 (but not 10.13.4) and not affecting Canary, Yandex or Opera.
    I’ll do some more digging and update this thread.



    Turns out the culprit is Kaspersky Internet Security which I installed about the same time as the upgrade to High Sierra 10.13.5.
    It has optional browser extensions for Chrome, Safari and Firefox.
    However I did not have those extensions activated.

    It was only when I turned off Kaspersky Protection completely that those browsers started working as expected.

    So the problem’s in Kaspersky – I’ll either have to get Kaspersky to fix it or use another security product.

    Thanks for your help.

    Hey Adrian,

    That’s awesome news! Glad to hear you eventually figured it out 🙂

    Feel free to let us know if there’s anything else you need and we’ll be happy to help.




    Narrowed it down to a checkbox in Kaspersky Internet Security.

    Under KIS Preferences/Protection/Web Anti-Virus,
    if I deselect “Check Secure Connections (HTTPS)” then the jetpack facebook widget works OK.
